How fast does the water temperature increase?

Here are the caveats:

1. Ambient Temperature (if it is colder outside, it takes longer to heat the tub)
2. Cover In Place (it will take longer if the cover is off - keep the cover on while heating the water)
3. All components are in good working condition

When you take these factors into account:

The spa will heat between 3 to 6 degrees per hour.

Based on certified testing for C.E.C. Title 20.

Your actual cost may vary depending on your local utility rates, local climate conditions and your actual usage of your Nordic hot tub.

The Nordic Hot Tubs are Environmentally Friendly with their insullation.

• 2 Pound Density Foam
• Title 20 Certified Insulation

The Appliance Efficiency Regulations include standards for both federally-regulated appliances and non-federally-regulated appliances. Twenty-three categories of appliances are included in the scope of these regulations. The standards within these regulations apply to appliances that are sold or offered for sale in California, except those sold wholesale in California for final retail
sale outside the state and those designed and sold exclusively for use in recreational vehicles or other mobile equipment.

R Value

is a measure of the capacity of a material, such as insulation, to impede heat flow, with increasing values indicating a greater capacity. A R value of 6 holds heat better than a R value of 1. If you live in Montana the recommended R value for your home should be 6 compared to an R value of 3 if you live in Georgia.

Typical R Value for Nordic Hot Tubs:

Insulation	R Value
Standard Insulation Package	12
Title 20 Upgrade	38

The Title 20 option has its origins from the State of California.

It is a requirement for improved energy efficiency (aka better insulation). For this upgrade, your tub is built with standard insulation, then we attach a vinyl backed insulation on the inside of the cabinet.

Customers have indicated the savings could be as great as $0.50 per day in electricity. Although the actual savings is based on quite a number of variables it is possible the Title 20 insulation upgrade could pay for itself within 12 months.

Hot Tub Cover R Value

The typical cover is 1.5 lb. density foam and with the vinyl cover, the R Value is 7.55.

Definition: The R-value is a measure of the heat loss for insulation under specified conditions.

The primary way heat transfer is slowed down by insulation is convection of the three modes of: conduction, convection, and radiation. A good insulator trap air which reduces convective heat loss leaving only conduction and radiation transfer. The primary role of insulation is to make a material that traps stagnant air.

Our Nordic Tubs use 2 lb. foam which is shown to provide an unbroken layer of insulation across all areas where it is applied.

Your first month electric bill.

After you purchase your Nordic Hot Tub, you will see a spike in your electric bill. The first months bill is going to be the highest due to the cost off heating the spa from cold to the desired temperature.

Filter Cycle Setting

Another thing to check is the filter cycle. You may also want to make sure the filter cycle is set on 2 or 3. If it is set higher it can cost more to run.

Extra Insulation

Nordic has an option at the time of purchase to increase the internal insulation - called Title 20 (refering to a Calif. state law). The cost for the title 20 given prior is for it to be installed here at the factory as the tub is being built before it is assembled. In order to install it at your home the tub will have to be disassembled the tub, install the insulation and then reassembled it. Check with the Nordic Dealer who to see if they can perform this at your home.
